[development] Making a whole site location aware - a design question

[Dave Cohen]

Consider...

Write a module which stores this data however you see fit.  (Could be a table 
you create that joins the users table on uid).

Then, use hook_db_rewrite_sql to filter out any nodes which have location 
information which is not within the users radius.  This way, your work 
applies to any node with location information, not just events.  And the 
event (or any other) module does not have to change at all.

If you take this approach, your module is essentially a location-based access 
control module.  Read up on how node.module uses hook_db_rewrite_sql to 
filter nodes based on the node_access table and emulate that.
